ABSTRACT:
A stator bar winding of a slotless-core electrical machine comprises conductors enclosed in an insulating sheath with the conductors arranged in three concentric layers. Conductors of the inner layer are placed underneath every second conductor of the middle layer, whereas the conductors of the outer layer are placed over every other conductor of the middle layer. The conductors of the middle layer are bent in their overhang portions from the axial direction to the angle (90.degree.-.alpha..sub.1) which is twice as small as the angle 90.degree.-.alpha..sub.2) to which the overhang portions of two other layers are bent. The conductors of the middle layer are also electrically connected in series and alternately to respective conductors of the outer layer or inner layer.
